Originally from the anime "Genesis Climber Mospeada" (where it was knonw as the Legioss), the Alpha Veritech was one of the primary mechs used by the Robotech Expeditionary Force in their battle against the Invid. Able to link to the larger Beta (TREAD) fighter for extra power and weapons systems, operate in both atmosphere and space, and transform into a humanoid battloid form for ground combat, it was a doughty combatant. And its deceptively complicated transformation sequence has made it a (BLEEP)-and-a-half to render into Lego.

Often referred to as the "Blue Alpha" for the most common unit coloring, the VFA-6H is the standard model.

The VFA-6I is specialized for reconnaissance, and has extra sensor systems in the head (and presumably elsewhere).

The VFA-6Z is optimized for atmospheric combat, sacrificing fuel capacity for extra thrust.
